Structure Introduction and transmission system The operational principle of LJC vertical extrusion pipe machine is : the main mortar leads the discharge head rotation inside the pipe mould through main axle of the machine , and depends upon the discharge head and main axle's dead weight, exerting the pressure to the concrete inside the mould by presser foot which is on the discharge head . The concrete joins unceasingly in the pressure of the discharge head, and becomes dense then shapes the pipe gradually. key component of the machine has: Main frame, power system, jacking system,(lifting system), internal water system ,mould, working platform, pushing car , power distribution part and so on. Our company is a professional manufacturer of cement equipment. For over 20 years, our company has developed many kinds of water conservancy machinery.
